P. A. WOOSTER' DISPENSING DEVICE Filed Sept. 30. 1931 2 My W A p ma Pam: A e-1s, 1933 UNITED STATES PATENT; OFFICE mm A. woosrna, or saw rmcxsoo, cum-01mm I msrans me imvrcn Application mes September so, 1931 Serla1 il'o.586,057.

My invention relates to improvements in dispensin devices, and particularly of the type use for dispensing powdered soap wherein the. outlet and dispensing passages are rendered accessible for cleansing purposes to dislodge accumulations of powdered soap which might tend to prevent a proper operation of the device. v

Devices of this type, including, in combination, a receptacle having a reciprocating valve movable to dispense a predetermined quantity of soa or other commodity, .are common, and one of the objects of the present invention. is to improve upon the construction and arrangement of such devices to the end that the passages may be easily rendered accessible for cleansing purposes and to remove any accu I mulation of soap or other commoditywhich may interfere with the proper operation of the device.

A still further object is to rovide a new and improved soap dispensing evice wherein the soap being dispensed willbe discharged vertically between vertical walls while fall- 2 'ing freely, through the action of gravity, to

prevent, as far as possible, the accumulation of a dispensed commodity within the discharge passages. .I accomplish these and other objects by means of the improved device disclosed in the drawing forming a part of the present appli cation, wherein like characters of, reference are used to designate similar parts throughout the specification and drawing, and in which-'- Fig. 1. is a side elevation, partly in'ver-tical section, disclosing my improved dispensing device;

Fig. 2 is a transverse sectional view-taken on line a-s of Fig. 1 in the direction indicated; and Fig. 3 is a broken dis nsing passage.

fie invention comprises a receptacle 1, for containinga commodity to be dispensed, such plan-view disclosing the as powdered or flake soap, and has its upper and lower ends 0 ned. The upper end is closed by means 0 any suitable cap 2, while the lower end is threaded or otherwise secured to a housing 3, saidhousing 3 being provided with a chamber 45idirectly below and communicating with the bottom opening of the receptacle 1, said chamber 4 in turn being provided with a vertically disposed dispensing passage 6 whose lowerend 7 is normally closed with 56 a suitable plug 8. a

' A valve casing 9 intersects the passage 6 and is provided with a vertically disposed outlet 11, preferably parallel with andofisetfrom thepassage 6, the purpose of which will hereinafter-be more fully set forth.

Slidably mounted for reciprocal or longi tudinal movement within the valve casing 9 I have provided a valve 12 held against rotation within said valve casing by means of a suitable screw 14 mounted within the housin I 3 and engaging a longitudinally disposed s otor groove 16 within said valve 12, as disclosed in Figs. 1 and 2 of the drawing.

The valve 12 is also provided tically disposedr lateral dispensing aperture 17 intermediate the ends thereof, said aperture'17 being arranged to register with either the discharge passage 6 or'the outlet 11 of the valve casing 9, but a spring 1 8'is interposed between the inner end of the valve 12. and the casing 9 and is arran ed to normally urge the valvel2 outwardly rom saidcasing to register the aperture 17 with the discharge;

assage 6, said outward movement being ad- Justably limited by means of ascrew-threaded cap 21 through which projects a suitable stem 22 by means of which said valve 12 may be moved, against the tension of the s rin 18, to

register the aperture 17 therein with t e outwith a ver- 1 dry, powdered soap, or the like, which readily flows intothe chamber 4 and a predetermined quantity-of said soap flows into and ilgls the dispensingaperture 17 of the valve When itis desired'to dispense this predetermined quantity the valve 12 is moved to its extreme ;inward' position, by means of the exteriorl ,extending-stem 22, against the tension of t espring 18, in which position the di nsing aperture 17 of thevalve 12 will register with the outlet 11 when the quantity of soa within said aperture 17 will bedispense by. the action of gravity, through said outlet 11.

When the stem 22 is released the spring 18 will urge the valve 12 to its outermost position withthe'aperture 17 in registration with the discharge passage 6, when it will again be filled, ready for the next operation.'

The vertically disposed outlet 11 provides accessibility to theaperture 17 when registered therewith, so that any accumulations ma be easily and readily removed through sai outlet 11. 1 v

Should the discharge passage 6 become clogged, the plug 8 may be removed, thereby giving access tosaid passage when the aperture 17 is registered therewith, whereby any grccumulation may be readily removed there:

I have also provided the inner end of the valve 12 with. a reduced projection 23 on the inner end thereof, which engages a vsimilar projection cast or otherwise formed on the mner end or wall of the valve casing 9, in order to limitv the inward movement of the said valve 12, and at the same time leave a space between the inner end of said valve 12 and the casing 9 when the aperture17 of said valve is in register with the outlet 11 of the casing 9. a 7

Similarly, a'chamber is formed on the oposite or outer'end of the valve 12, when in its outermost position with its aperture 17 in registration with the discharge passage 6, by means of the cap 21. Both chambers thus produced are provided with suitable vents 26. As the plunger or valve 12 is reciprocated, should any small uantity of the commodity being dispensed nd its way between said valve 12 and the walls of the casing 9, such matter will eventually be pushed, by the blunt ends of the valve 12, into one or the other of the chambers thus formed and eventually such matter will be pushed out of said chambers, and casing 9, thereby making the device automatically self-cleaning. Having thus described my invention, what I claim as new and desire to secure by Letters Patent is- 1.
